A tank is in the form of inverted right circular cone 8 m across the top and 10 m deep (as shown in the figure). If it is filled to the height 8 m with oil weighing 950 kg/m3, solve the work done in pumping the oil to the top of the tank.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

If it is filled to the height 8 m with oil weighing 950 kg/m3, solve the work done in pumping the oil to the top of the tank. Hint: the number of newtons of force necessary to lift an element is the product of kilograms of mass and 9.81, the numbers of meters per second squared in the acceleration due to gravity.
